What a finished MKT-832 Topic 8 mediated behavior research design looks like
The finished design pairs a quasi-experiment with data the researcher collects directly. Its core is a difference-in-differences comparison of purchase behavior in the two countries where counts disappeared against comparable countries where they remained, over matched periods before and after the change. Salganik's account of digital trace data frames the threats: the logs are always on and nonreactive, yet drifting and algorithmically confounded, because the ranking system changed alongside the counts. The design responds with a consented panel of users who complete short surveys on what they considered and why, linked to their own activity records. Lazer and colleagues' analysis of Google Flu Trends is cited as a warning about platform systems that change underneath a model. Every threat to validity is listed with the specific check that addresses it, and the analysis plan is preregistered.
How an MKT-832 Topic 8 example is structured
The design opens with its research question and states why platform data alone cannot answer it. The natural experiment comes next, with the rollout, the countries affected and the reasons the platform gave for choosing them, since a non-random choice is the design's first threat. The comparison section explains how control countries are selected and how parallel trends before the change are checked. Data sources follow in two parts, platform records obtained through a research agreement and the consented panel, with what each can and cannot observe. A threats table lists drift, the simultaneous ranking change, selective attrition from the panel and spillover through users who follow accounts abroad, each paired with a check. Ethics and consent receive a section of their own. The design ends with its preregistered hypotheses and the result that would count against them.
A question platform logs cannot settle
Whether visible popularity changes buying needs a comparison the logs do not contain, so the design begins by naming the counterfactual it has to build.
Two countries and a non-random choice
The platform picked the first countries for its own reasons, and the design records them because they could correlate with shopping behavior independently of the change.
Parallel trends checked before any claim
Purchase patterns in treated and comparison countries are compared over the year before the change, and the analysis proceeds only where they moved together.
A ranking change hiding inside
Hiding counts also altered how posts were ordered, which Salganik would call algorithmic confounding, so the design seeks periods and surfaces where ranking stayed fixed.
A consented panel beside the logs
Short surveys on what users considered, linked with permission to their own records, supply the reasons that activity data alone cannot capture.
Hypotheses registered with a disconfirming result
Predictions and the analysis plan are filed before data access, including the pattern of results that would show visible counts made no difference at all.
Where marks go in MKT-832 Topic 8
Treating platform data as though it were collected for the researcher's question is the first thing a committee marks down, since the platform chose what to record and when to change it. A rollout described as a natural experiment without asking why those countries went first costs heavily, since the choice itself may correlate with the outcome. Many drafts overlook the ranking change that accompanied the count removal, leaving two treatments tangled as one. Parallel trends are often assumed instead of checked. Designs relying only on logs cannot say why behavior changed, and those relying only on surveys cannot say whether it did. The ethics section is commonly reduced to a sentence, though linking survey answers to activity records demands consent and data-access terms a doctoral committee will read closely.

MKT-832 Topic 8 questions, answered
What is algorithmic confounding?
A term Matthew Salganik uses for the way a platform's own systems shape the behavior recorded in its data. If a recommendation engine or a ranking change pushes users toward certain actions, the logs show those actions, and a researcher may mistake the system's influence for a fact about people. The example treats the ranking change that accompanied hidden counts as exactly this problem and designs around it.
Why combine platform data with surveys?
Each covers the other's blind spot. Platform records show what people did, at scale and without the distortion of asking them, but not what they considered or why. Surveys capture reasons and alternatives but rely on memory and self-report. Linking the two, with consent, lets the design check whether a change in behavior matches a change in stated reasons, which neither source could establish alone.
What did the Google Flu Trends case teach researchers?
Lazer and colleagues showed that a model estimating flu prevalence from search queries drifted badly, partly because the search engine itself kept changing in ways that altered what people searched. Their warning against what they called big data hubris applies directly to consumer research on platforms, where the system producing the data is redesigned constantly. The example cites the case when planning its checks for drift.
